DATA EXCHANGE - TRANSMISSION MODES

Question 1

What are transmission modes?

Answer 1

Ways in which devices on a network communicate with each other and transmit data

Question 2

What are the 3 types of transmission modes?

Answer 2

Simple/ full-duplex/ half-duplex

Question 2

What is the SIMPLEX transmission mode?

Answer 2

Signals go in one direction at a time

Question 3

What is the FULL-DUPLEX transmission mode?

Answer 3

Signals go in both directions at the same time

Question 4

What is the HALF-DUPLEX transmission mode?

Answer 4

Signals go in both directions but the devices don’t transmit at the same time

Question 5

What is the data transfer of a SERIAL transmission mode?

Answer 5

Bits of data are transferred one at a time over a wire

Question 6

What is a benefit of a SERIAL transmission mode?

Answer 6

Good over large distances

Question 7

What is a limitation of a SERIAL transmission mode?

Answer 7

Complex because data has to be broken down into individual bits

Question 8

What is the data transfer of a PARALLEL transmission mode?

Answer 8

Bits of data are transferred at the same time over a wire

Question 9

What is a benefit of PARALLEL transmission mode?

Answer 9

Faster because more bits are transferred per second

Question 10

What is a limitation of PARALLEL transmission mode?

Answer 10

Shorter distance, maximum about 5 metres
